Gibson (7-6) allowed seven runs on five hits and four walks over 4.1 innings Monday, striking out two and taking a loss against the Padres.

Gibson coughed up a two-run shot to Manny Machado in the first inning and set the tone for a poor performance. The Padres scored another pair in the third inning before piling on four more runs in the fifth. Gibson has given up 15 earned runs over 14.1 innings in his last three starts, driving his season ERA up from 3.99 to 4.54 in the process. Since his last win July 7, he's gone 0-3 with a 5.86 ERA over eight outings. Gibson is projected for a road matchup with the Yankees this weekend.

Wheeler came away with a no-decision in Monday's 3-2 extra-inning win over the Astros, giving up two runs on six hits and two walks over six innings. He struck out six.

The veteran righty fired 64 of 97 pitches for strikes in his NL-leading 20th quality start of the season, tying him with Seattle's Logan Gilbert for the major-league lead. Wheeler has produced a quality start in all five of his trips to the mound in August, posting a 1.97 ERA, 0.91 WHIP and 37:5 K:BB through 32 innings on the month. He'll look to keep bolstering his Cy Young credentials in his next outing, which is scheduled to come at home this weekend against Atlanta.

Williamson (shoulder) is scheduled to make a rehab start for Triple-A Louisville on Tuesday, C. Trent Rosecrans of The Athletic reports.

Williamson, who threw two innings at the Reds' complex in Arizona last Thursday, is scheduled for three innings in what will be the first appearance of his second rehab assignment. The left-hander opened the season on the injured list due to a left shoulder strain and was pulled off an earlier rehab assignment in June, when he was diagnosed with a Bennett lesion in the shoulder.

Cabrera (2-6) took the loss against Colorado on Monday, allowing three runs on six hits and two walks while striking out eight batters over 5.1 innings.

Cabrera had his swing-and-miss stuff working, as he induced 18 whiffs en route to eight punchouts. The right-hander got through four frames without giving up a run but faltered late in his outing, yielding two runs in the fifth and one in the sixth before departing. Cabrera ended up with his third straight loss, and he also walked multiple batters for his eighth consecutive start. He has a healthy 81 strikeouts over 70.2 innings this season, but Cabrera has also issued 40 free passes, and his 5.09 BB/9 is second-worst in the league among pitchers who have thrown at least 70 frames.

Feltner allowed two runs on seven hits and two walks while striking out two batters over five innings in a no-decision against Miami on Monday.

Feltner pitched for the Rockies for the first time since landing on the injured list with a right shoulder strain Aug. 8. The right-hander was able to go five innings and throw 71 pitches in his return, and he got through four scoreless frames before faltering by allowing two runs in the fifth. Feltner notched only six whiffs and posted just two punchouts, but he didn't give up any extra-base hits. He's allowed three or fewer earned runs in each of his past nine starts, though his 36:19 K:BB across 46.2 innings during that stretch isn't very impressive.

Parker (7-8) took the loss against the Yankees on Monday, allowing two runs on five hits and two walks over four innings. He struck out five.

Parker gave up a leadoff home run to Gleyber Torres and had to battle his way to get through four innings, just allowing two runs. Parker's up-and-down campaign continues, as he's allowed two runs or fewer in five of his last six starts, but in between those games he allowed nine runs vs the Phillies. The 24-year-old rookie will carry a 4.26 ERA in 126.2 innings into his next start.

The Phillies recalled Mercado from Triple-A Lehigh Valley on Monday, Matt Gelb of The Athletic reports.

He'll take over the roster spot vacated by Jose Alvarado, who has been placed on the restricted list as he deals with a personal matter. Mercado was moved to the bullpen at Lehigh Valley after being demoted around the All-Star break and has collected a 2.92 ERA and 12:8 K:BB over 12.1 frames covering his last 10 appearances.

Cardinals manager Oliver Marmol said Monday that Matz (back) will have his pitch count scaled back to 65 in Tuesday's rehab start with Triple-A Memphis, Lynn Worthy of the St. Louis Post-Dispatch reports.

That's after he threw 85 pitches in his last outing with Memphis. The idea behind reducing Matz's workload is to keep him flexible for a variety of roles when he rejoins the Cardinals, as it sounds like he could be used as a starter or a reliever or both. Tuesday's rehab appearance is expected to be the final one before Matz is activated from the 60-day injured list. He's been out since late April due to a herniated disc in his back.

Lynn (knee) will begin a rehab assignment with Triple-A Memphis on Sunday, Lynn Worthy of the St. Louis Post-Dispatch reports.

Lynn threw approximately 75 pitches in a live practice session Monday and is slated for 80-to-85 pitches in his first rehab start. He should be stretched out enough for a return to the big leagues after that, though it's not a guarantee that he'll rejoin the St. Louis rotation at that time. Lynn has been out since late July with right knee inflammation.

Wicks (oblique) will make another rehab start with Triple-A Iowa on Friday, Meghan Montemurro of the Chicago Tribune reports.

Wicks struck out four over 4.2 scoreless innings Sunday with Triple-A Iowa, throwing 73 pitches. However, he will be asked to get a bit more stretched out before likely rejoining the Cubs' rotation next week, likely on Sept. 4 against the Pirates. Wicks has been sidelined since mid-June with a Grade 2 right oblique strain.
